The infinite loop of "Scan & Repair" is one of the most common issues that players face with their Call of Duty: Warzone, Black Ops Cold War and Vanguard games when launching via the Battle.Net launcher. Now it has once again returned for Vanguard players right after the game's launch.
You have probably come across a random game crash with the following "Fatal Error" message.
You would have pressed the "Scan and Repair" option from this Fatal Error (like any normal person would do), which leads to an unlimited loop of "Scan & Repair" in your Battle.Net launcher, not allowing you to enter the game. You then might be shown yet another error with the code BLZBNTAG00000BB8 (the code might differ slightly depending on which game it is happening for you).
Normally, you would press the "Scan & Repair" option by clicking on the gear icon next to your launcher's "Play" button. But, at this point, even it won't work.
Blizzard Customer Support suggests deleting the .IDX files in the data folder of your game directory. However, you've likely arrived here because that solution doesn't always work.
